Configurable safety modules – As easy to use as a safety relay, as flexible as a safety controller

Configurable safety modules

As easy as a safety relay, as flexible as a safety controller: With our configurable safety modules, you can implement solutions efficiently with as little as three safety functions. Thanks to the TÜV-certified software, you do not need any programming knowledge to create the safety logic. Thanks to the modular design, the functionality can be flexibly adapted and extended to meet your requirements.

Product List

PSRtrisafe safe extension modules

Safe extension modules for an individual safety solution

Configuring safety modules flexibly

The PSRtrisafe safety module is a configurable small-scale controller. It enables you to monitor several safety functions in a single application. It is easy to create the safety logic using the SAFECONF software and drag and drop.

The system functions as a stand-alone solution and can take over the entire machine control system in smaller machines. You can use the basic module as a separate component for this purpose. You will get the following features at an overall width of 67.5 mm:

  • 20 safe input signals for evaluating safe sensors
  • Four safe outputs (up to category 4)
  • Clock, alarm, and ground switching outputs
  • Contact multiplication or contact amplification possible via external contactors in conjunction with integrated monitoring

Extending your safety system

If there are not enough I/Os, you can extend the system by adding up to 10 safety-related extension modules, which are easily connected to the master module via the DIN rail connector. This gives you access to additional I/Os for connecting more sensors and actuators.

The modular safety technology can be incorporated into existing networks via a gateway.

PSRtrisafe combines functionality and flexibility, and closes the gap between simple safety relays and programmable safe controllers.

SAFECONF configuration software

SAFECONF configuration software

Intuitive configuration without programming knowledge

You use the free-of-charge SAFECONF configuration software to configure the modular safety system. No programming knowledge is required in order to use the configuration software. This is because you create the safety logic graphically using drag and drop, and can flexibly adapt the safety functions as you wish. The integrated simulation enables you to perform a full function test of the safety logic once created, without any hardware. All function blocks have been certified by TÜV.

A step-by-step guide to the software

1. First of all, choose the blocks you need from the toolbox, which contains a variety of safe functions. Then drag them with the mouse to the connection area.
2. Connect your blocks to the required inputs and outputs, which you also drag and drop to the connection area, before wiring them virtually there.
3. Finally, download the tested safety logic into the safety module using a standard USB cable.
4. Should you have any questions about software functions, there is a help feature containing functional descriptions and example applications.

Comprehensive diagnostics directly on the device

Diagnostic LEDs indicate the states of all inputs and outputs of the PSRtrisafe safety modules. In addition, signal outputs indicate the switching states, e.g., on signaling devices. The safety module communicates with the higher-level controller of your machine or system via the fieldbus coupler. This enables you to easily integrate your safety functions into visualization systems or remote diagnostics. Errors can be found and rectified more quickly.
